Everyone may have different ideas, but I personally think Laifu is better.
Because I think Laifu means bringing blessings. Everyone hopes that they will have continuous blessings and no disasters. I think the name of the dog Laifu has a very good meaning.
Not only does it bring luck to the dog itself, but it also brings luck to the dog’s owner and the dog’s home.
Dogs are human beings’ good friends and are often regarded as the mascot of the family by many people. Therefore, you can choose some more auspicious words to name your dog from the perspective of being beneficial to the family. For example, there is a dog named "Wangcai" in Stephen Chow's movie.
The name "Wangcai" comes from the perspective of being beneficial to the family, hoping to bring good fortune to the whole family, and the meaning is quite good.
